Runtime Studio OFFICIAL SALE

Runtime Studio - Runtime Editor Framework


Building an in-game editor takes months. You need UI systems, selection tools, transform gizmos, saving, and safety checks so players don’t break your game.


Runtime Studio gives you a sandbox-style user-generated content system for your game, where players can create, edit, save, and load levels directly in-game.


Instead of building everything from scratch, you can add a playable creation layer in minutes.


Players can export and import their creations as files, making it easy to share content outside the game.


Runtime Studio is flexible and fits into sandbox or creation-focused games where players can build and test their own levels.

Powerful Editing Workspace

Give your players a familiar and powerful workspace.


Runtime Studio includes a UI Toolkit-based shell with Hierarchy, Project, and Inspector panels. Players can interact with scene content using action panels, a console overlay, and a smart object picker.


Runtime Scene Editing

Editing levels feels intuitive and familiar.


Players can build worlds using Move, Rotate, and Scale tools with transform gizmos, free camera controls, grid overlays, snapping, and live asset previews.


Player-Safe Components

You control exactly what players are allowed to edit.


Runtime Studio includes runtime inspectors for many common Unity components, allowing players to interact with gameplay systems directly inside the editor.


You can also expose custom gameplay components like Health or Spawners by integrating them into the runtime inspector, with full control over how they are presented and edited.


Runtime Play Mode

Test levels instantly by switching between edit and play mode.


Runtime Studio includes a built-in Play Mode that allows players to switch from editing into gameplay. Players can run their level in real time, test mechanics, and experience their creation as a game, then return back into editing to make adjustments without losing progress or context.


Save, Load, and Share

Player-generated content needs a reliable way to be stored and distributed.


Runtime Studio includes a complete runtime save and load system. Creations can be exported as compressed package files, allowing players to share custom levels via external distribution.


Curated Asset Libraries

You decide exactly what assets players can use.


The Editor Asset Library lets you group prefabs, meshes, materials, and audio. Players can browse these curated assets in the runtime Project panel with automatically generated previews.


WebGL Support

Run and share user-created content across platforms.


Runtime Studio supports WebGL builds, allowing your runtime editor and gameplay systems to run in browser-based environments. Level export and import is fully supported through compressed package files, enabling players to transfer creations between sessions and platforms using external file handling.


Built-In Undo and Redo

Mistakes happen.


Players can safely undo or redo edits, including transform changes, component edits, object duplication, and hierarchy modifications.


Extensible Framework

Build and expand the editor to fit your game.


Runtime Studio is a modular, extensible framework that allows you to add custom tools, components, and workflows. Extend the runtime interface with your own systems or create new editor features through plugins or direct integrations, tailored to your project’s needs.
